LUBRlCATlNG-OIL CUP.

SPECIFICATION forming part of Letters Patent No. 314:,695, dated March 31, 1885.

Application filed February 12, 1885. (No model.)

To all whom it may concern.-

Be it known that I, JOHN E. LONERGAN, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Lubricating- Oil Cups; and I do hereby declare the following to be a full. clear, and exact description ofthe same, reference being had to the annexed drawings, making part hereof.

The object of my invention is to provide a lubricating-oil cup with a feed-regulating device, which will not be affected in its position by the loosening or tightening down of the cover or cap of the cup, which forms a joint upon the upper edge of thelatter, whether the feed be open or closed. sustaining the valve-stem, which is moved upward and downward to regulate the feed, in place by a device whichsets upon and is rigidly attached to the top of the base in the interior of the cup, as will be more fully hereinafter described.

The nature of my invention will fully appear from the following description and claims.

In the drawings, Figure 1 is a vertical longitudinal sectional view of my device; Fig. 2, an elevation of the same with the cover of the cup and the upper cap removed; Fig. 3,a perspective view in detached parts, showing the valve-stem, the cone-valve, part of the spiral spring around the stem, the catch or lug which holds the valve open, with its screw-threaded sleeve which envelops the stern, and the knob which is attached to the upper end of the stem to raise and lower the same; Fig. 4:, a detached perspective view of the slotted sleeveand upper part of the stem, showing the position of the latter when the valve is open.

A is the glass shell of the cup of my lubricator; B, the base of the lubricator, pierced with the vertical central opening, G, which is flared at its upper part to receive the conevalve D and form a seat for the latter; E, a vertical. cylinder cast upon base 13, and having openings F F, which latter permit the oil to flow from the cup into the opening G when the valve is open.

G is the round cover of the cup A, provided with a large central opening and downwardlyprojecting flange G, which is screw-threaded internally.

This I accomplish y The upper outward surface of cylinder E is screw-threaded, and the cover G, by its screw-threaded flange G". is screwed downupon the upper end of the cylinder E until it sets down upon the upper edge of the glass cup A. This cup Ais narrowed toward its lower edge, as shown, and sets down upon the upper surface of the base B. Around the upper and lower edges of the glass cup I einploy a strip; H H, of cork or other suitable packing material. The lips I I of the cover G and the base B overlap the upper and lower edges, respectively, of the glass cup, and hold it securely in place when the cover G is screwed tightly down upon the cylinder E. A screwthreaded plug, J, sets into the interior screwthreads of the cylinder E. (See Fig. 1.) The plug J terminates above in the standard K.

L is the valve-stem, which is screw-threaded at itsupper end for sufficient distance to re ceive the internallyscrew-threaded sleeve M and knob N.

O is a laterally-projecting lug or catch rigidly attached to the sleeve M, and is of sufficient length to rest upon the upper edge of standard Kwhen the stem is raised and turned to open the valve by resting upon the upper edge of standard K, as it will be perceived by referring to Fig. 1 that the valve will be held open.

P is a compressed spiral spring surrounding the stern L, and setting below against the upper surface of the cone-valve D, and above against the under surface of the internal plug, J, whereby the tendency of this spring, when not checked, is to drive the valve D closely into its seat. The surface of the stem L is plain at the part within and below the plug J, and moves freely upward and downward in said plug. The stem L terminates at its ex.- trerne upper end in a chisel-edge, Q, similar to that of a screw-driver. of the knob N is provided with a slot or groove, It. By removing the knob N and reversing it its groove It will receive and engage with the fiat or chiseled edge Q of the stem.

For greater security against accidental turning of the stern, in practice I serrate or mill the upper edge of the standard K, and the lower edge of the lug O is made sharp enough The upper surface to engage with the milling or depressions thus formed. The downward pressure of the spiral spring P is so great upon the stem that the sleeve M and its lug 0 will be held down so firmly as even to permit a turning of the stem Without disengaging the lug 0 from the milling of the standard K. Therefore, when it is desired to change the quantity of feed through the valve when the latter is open,the groove of the knob N is applied to the edge Q of the stem, and the latter is turned in one or the other direction, according to the desire to increase or lessen the feed, and the screw-threads of the stem, engaging with those of the plug M, will raise or lower the stem, and will lengthen or shorten the distance of the sleeve M from the valve D, and thus increase or decrease the distance of the valve D from its seat when the valve is open and the catch 0 rests on standard K. WVhen the valve has thus been satisfactorily regulated or adjusted, theknob N can be removed and screwed again upon the upper end of the stem until its lower edge sets tightly against the upper edge of sleeve M, when it will act as a lock or check nut to secure the latter against turning upon the stem.

S S are two openings through the downwardly-projecting flange G, through which the cup A may be replenished with oil when desired. T is a thimble or cap screwed over an upwardly-projecting flange U upon the cover G.

The cap or thiinble T is designed to protect the working parts from dust.

The operation of my device is as follows: When the valve D is at rest in its seat, and it is desired to feed oil to the bearing which the apparatus is designed to lubricate, and upon which it is set in the well-known way, the cap T is removed and the stem L is raised bylifting the knob N. A turn of the knob will then turn the stem L and sleeve M until the catch 0 is over the upper edge of standard K. The knob is then released and the catch will rest upon the standard and hold the valve open, and the oil from the cup will pass, as described, in small regular quantities through the opening 0 to the bearing to be oiled. The valve is closed by reversing the above operation.

When it is desired to again use the valve, the operation of opening it is repeated, and the feed will be the same as that previously employed. If the valve or its seat should become more or less coated with impurities, the stem M can be raised as high as the compressed spring will permit,and then, suddenly released without turning it, the valve will shoot with great rapidity and force under the influence of the spring back into its seat. This operation repeated several times will rub the impurities from the valve and its seat. If at any time it suddenly becomes necessary to supply over, when by dropping the stem until the catch 0 rests upon the upper edge of standard K the previous regular feed will'be renewed without readjustment or resetting of the valve being required.

The cylinder E may consist of a mere shallow collar, supported rigidly by standards,

which are rigidly attached to the base 13. In

upper part of base-opening O, stem L, with its spring 1?, sleeve M, upon the upper part of said stem, provided with the catch 0, by the raising and turning of which stem the catch 0 is made to set upon the top of standard K, whereby the valve can be always opened at a regular feed, arranged and operating substantially as described.

2. In a lubricating-oil cup suitably inclosed at the top, the combination of shellA, base B, central open cylinder, E, supported rigidly from said base, plug J, set in the upper part of said cylinder, standard K, valve D in the upper part of base-opening O, stem L, with its spring I, sleeve M, screwed upon the upper part of said stem, provided with the catch '0, the said stem being adapted by its screwthread to be turned in the screw-thread of the sleeve M, to shorten or lengthen the distance of the sleeve M from the valve D, whereby the quantity of the feed of oil from the valve can be regulated or changed at will, substantially in the manner above set forth.

3. In a lubricating-oil cup suitably inclosed at the top, the combination of shell A, base B, central open cylinder, E, supported rigidly from said base, plug J, set in the upper part of said cylinder, standard K, valve D in the upper part of base-opening O, stem L, with its spring P, sleeve M, screwed upon the upper part of said stern, provided with the catch 0, the said stem being adapted by its screwthread to be turned in the screw-thread of the sleeve M, to shorten or lengthen the distance of the sleeve M from the valve D, whereby the quantity of the feed of oil fromthe valve can be regulated or changed at will, and the knob N, screwed upon the top of stem L and setting down upon the sleeve M, to serve as a check or look nut to the latter, substantially as described.

4. In alubricatingoil cup suitably inclosed at the top, the combination of shell A, base B, central open cylinder, E, supported rigidly from said base, plug J, set in the upper part of said cylinder, standard K, valve D in the upper part of base-opening 0, stem L, with its spring P, sleeve M, screwed upon the upper part of said stem, provided with the catch 0, the said stem being adapted by its screwthread to be turned in the screw thread of the sleeve M, to shorten or lengthen the distance of the sleeve M from the valve D, whereby the quantity of the feed of oil from the valve can be regulated or changed at will, and the knob N, so grooved or indented at the top as to engage or fit over the correspondinglyshaped upper terminus of stem L, substan' tially as and for the purposes described.

5. In a lubricating-oil cup, provided with stem L and valve D, to close opening 0 in base B of the cup, the combination of the shell A, base B, central open cylinder, 'E, attached rigidly to said base and sustaining said stem L, cover G, open centrally and secured to the upper part of said cylinder, whereby it can be tightened or removed without disturbing the centrally-operating mechanism to open and close the valve or changing the feed, sub- 20 stantially as described.
